These are a couple of risers I made over the last couple of days. I couldn't find any I liked so designed and made these. A little complex to make these, with multiple procedures. I cut a couple of pieces off a 25 mm thick ally slab to rough size, then I worked out which bits to do first, which were the 22mm hole, then the two 6.5mm holes in the top. After that it was just a matter of chucking the bar clamp end in the four jaw. Once chucked, I turned it down to 40mm and drilled and tapped the bottom with a 10mm x 1.25 thread. Then turned it around and turned the top end down to 55mm and angled the leads in with the compound. Once that was done, I mounted a vertical slide on the cross feed, mounted an arbor with a 2mm slit saw in the chuck and cut the top clamps free. After that, it was just a matter of drilling the top clamp holes out to 8mm, with a 10 mm recess for the allen heads and tapping the lower holes 8mm x 1.25. And then polishing, filthy job. Wife hates it too, tramping black crap all around the place. But they turned out pretty good I think. I was going to make a couple more from some round stock, but these turned out so well, I stopped here.

I love polishing if I have the right machines. I don't like having to rig a buffing wheel to my drill press or lathe. I have the extra pedestal grinders to make some nice buffers....Just don't have the space to set them up.
But God....when something gets polished the wow factor and personal satisfaction goes through the roof. I love it. Anyway...I just found these buffing wheels that fit on my 4-1/2" grinders. I already have the polish....so when the wool buffing wheels come in, Im going to see how it works out. Thats another tool I love....angle grinders. So damned versatile.
Oh...Those risers look great TH

Wool buffing wheels for 4-1/2" angle grinders.

To speed up the process and get a good job, get yourself an 8" bench grinder, some sewn sisal wheels, sewn cloth wheels and loose leaf wheels to fit. You'll also need some bars of compound, black for roughing, white for polishing and green if you want to go that far. An nylon fibre wheel is indispensible if you have really rough surfaces.

The new Narva switch arrived a few days ago, still undecided on where to park it??? I made two brackets for it:, one hanging off the rear engine mount, the other a bit further back directly under the side panel. The switch isn't the best looking thing. so I turned up a two piece Delrin cover for it. A ring mount of Delrin with a .6mm lip is mounted between switch and bracket, once hooked up a Delrin cover is pushed over the mounting ring and held in place via a groove I machined inside the cover and the .6mm lip I machined on the the mounting ring. Mounted behind the the rear engine mount the cover is visible, mounted directly under the side panel only the switch face is visible. The cover just acting as a dust cover. Leaning toward the latter mount.

Master cylinder and clutch lever came this morning. I was going to put a kit through the stock master cylinder and buy a new clutch lever, until I discovered the kit was $78, then I had to fork out out for a new clutch lever as well. It appears the 74 TX came with a 5/8" master cylinder bore, all other years, the kits are only $35, just my luck. Anyway, I did some googling and found a master cylinder and clutch lever combo on Banggood for $65, so bought them. Pretty well made, levers are adjustable, but do require a largish hand, even on the closest setting. Levers are well made, master cylinder casting is a little rough, but good enough. I did want black bars with polished aluminium fittings, but settled for the opposite, chrome bars, polished aluminium risers and black fittings. They look all right though.
