Rack wanted to do for a very long time. And of course the stand should be as usual — “lightweight, durable, and reliable.” I must say, the only justification for the work done — “well, it’s FOR MYSELF, for many years, a good tool is never easy…”.
As I said earlier, the garage has two problems — precisely cut and evenly to drill. The problem with drilling solved, the stand for the drill was well worth the time and money on all hundred. Long gathered dust in the corner waiting for their grinder. It is the Bulgarian — made in the distant 1977 in Bulgaria on “ELPROM LOVECH”, is very heavy but, according to rumors, a very reliable GRINDERS. I tried to work with her. I considered myself if not cool spices, then certainly seasoned. Always worked great MAKITA 9069, the thing is quite powerful and heavy. But Bulgarian in comparison with makitas — wild animal. While similar to Manitou power 1.9 kW is significantly heavier, moreover, specifically my under the wheels of 180 mm and rotation speed at the output of 8500 rpm. so I decided then, that in hand it will take longer (stiff) and the way her stance. And stand wanted to do for a very long time. And of course the stand should be as usual — “lightweight, durable, and reliable.” I must say, the only justification for the work done — “well, it’s FOR MYSELF, for many years, a good tool is never easy…”.
I started as — welded rectangle for the base.
The base tube 50*50 and 45th area.
For the hinge taken rear hub, like the CHERY TIGGO. Cut it with the Central projection, blaine was the ABS sensor.
Rear hub from Chery Tiggo.
The hub is attached to the channel in which the hole cut for mounting. Cut grinder, quite hard by the way. Finished with a file.
The hole in the channel under the hub.
The main bracket for the Bulgarians started to do from the grinders. First, pull the corners to the standard fixing handles, then welded between them a third area.
Then bent the bracket clamp to the body grinders from 2 mm steel.
Bracket — clamp from 2 mm steel.
This clamp welded a bolt and linked the area with the fixing part. To the entire resulting structure welded pipe 50-50 with holes for fastening to the hub.
Mount the grinder.
With the bolt adjustable position grinder on the table. Further welded to the base 60 nd area — it will be attached to the channel. I estimate the location and drill the channel and the area under it. The bolts will be different — M10 and M12, is connected with the second adjustment, the channel should be slightly rotated due to the increased bolt holes.
Fixing of steel channel to the base.
Then welded two tube — guides for the clamping mechanism, as well as strengthened the construction of two segments of 50-th area.
Almost finished Desk.
Then on top of all this welded sheets with a thickness of 4 mm. As tried, and a perfectly flat surface did not work, drops to 1-1,5 mm are available, but in practice, the cutting accuracy is not affected.
Now it is possible to assemble the system. To additionally reinforce the corners of the channel and the main bracket. Total weight is even not critical, but is already quite interesting…
The first Assembly.
Then there was the long and dreary — outfit for work. This emphasis and the pressure for harvesting is the spring, it’s extender table. Let’s start with the stop for the workpiece. Take cut 50 angle welded to it a small rectangle.
The focus for procurement.
Now we have to cut him an arc, to cut the workpiece at any angle. Using the template first drill holes in an arc. Face piercing holes, then mill the arc completely.
Arc for cutting at an angle.
Now the clamping device. Screw taken from the old and bent the eighth of the Jack. I thought it was fair that it will be better than the usual Chinese studs. The end of the screw I ground off up to 6 mm and cut thread.
Old Jack went to the expense.
For the movable part the hard part is to make the axle. I did cut from the same Chinese hairpin, I should say — tokaku used to grind down to the desired diameter grinder, albeit with some adaptations.
The movable part. Worn without tokarki.
And it is already assembled and in its place.
The clamping device.
Left to secure the nut. The clamping device was planned to be removable, so attached to the bolts with cut threads directly in the desktop. The nut of the Jack scalded pieces of 4 mm steel.
Since clamping was ready, I decided to cut the pipe for the legs of the table, at the same time to see how it all works. The result made the cut on the blank workpiece in the gear case of the grinder rested. Also later cut the clamp across its width.
The clamping device is assembled.
By the way, the photo shows the nuts with wing nuts — with them I did one cut. Never use in places the nuts with wing nuts, manual efforts are not sufficient for good fixation stops. It is an invaluable experience — the nuts were loose, the disc shattered into pieces. Now there is the usual nut, always tighten very tightly.
On the recoil spring. Well as a spring… I thought it would be spring, but in the end something abruptly. I realize that he made it complicated, but the result was worth it. I’ve presented some powerful spring is needed to hold the grinder, and that stress at the end of the cut must be small. Besides, after cutting it is necessary to smoothly take the grinder up. And want to cut, let go and she GRADUALLY returned to its original position. What do you want? Gas filled strut the course, from nine, a long time lying on the shelf. And — return system must be hidden, that is, to work from the bottom. This means you will need additional traction and leverage. Actually do this quite easily, I would even say fast. First made the cut in the table under the lever. Lever itself is made of the area by many of the fittings, gave it the desired shape. The lever is mounted directly on the hub to a regular stud.
Lever return mechanism.
Need some more details — the actual gas stops, long pull to it, the yoke is bent from the M6 studs. The emphasis arose as there were. Worked the first time. At first it seemed that raises harsh, but when the grinder has acquired all sorts of handles and housing, it was at the time.
The details of the return mechanism. A mechanism in the provisions of the compressed-decompressed.
Well, actually it’s almost everything. Were still made the spark arrester — just a piece of tin fastened in the way of sparks. Even put a separate pen drive — pipe is screwed to the main bracket and to the tube staff side handle the grinder. Of course I made a table extension, on the principle of pipe-in-pipe. Here was an ambush inside the pipe includes pipe 50X50 45X45. It exists in principle, but in fact it is nowhere to be found. Had to weld 4 mm strips on the 40X40. The extension will be permanently two devices — additional — blank-blank needed to cut off part was not picked up by the disk and flew off, and for more emphasis for “cloning” items — if you need two or more items of the same length no need to measure the length before each cut.
Table extension and accessories on it.
Yeah, I forgot about the protective casing. Native cover was long lost, stood under a 230-th disk. I increased where the maximum and made him flip the part like the factory mounting hole.
Protective casing and movable part to him.
And only when it was time to paint, I saw the amount of detail “simple and easy” stands for Bulgarian. To move the unit better together. No, you can of course one… but very hard.
Ready to work.
After it became obvious a few of the factors complicating the work on the installation. First, we need a permanent place for her to carry back and forth just will not work, and you don’t always have an assistant for this. Second, we need to reduce the speed. At 8500 rpm not to work the drive 230, and 180-it’s not enough to prevent the clamping mechanism. Currently actively implementing in the system of adjustment of speed feedback below the target speed sags under load. Besides, it will be possible to use saw blades for metal (3000 rpm for 230 on disk) and wood (about 4000 rpm). And if desired, and 355 mm disc to stick, the truth will have the table finished and a new cover to do.
