Home-made tools

[RichardL]

Hello Folks,

While rebuiling my bike (as seen at "Bikes & Pictures" as Richard's 55 A10), I made a lot of tools (rather than spend big money). Here are a couple of pictures of one of them. Just for laughs, can you guess (or do you know) what it's for?

It's a Universal Adjustable Dinosaur Egg Cup for a man who likes his breakfast big .. . when you've made the grill for the toasted soldiers to go with, I'd like a set too. Groily

I could be rude but I guess Erling would throw me off the forum! Ermmm, fraid I dont have the foggiest Idea. ???

How long are we going to have to wait for the answer as this is going to play on me all evening/week!

Looks to me like a bearing puller maybe drive side main??.If not definatley a egg holder.. Dave....

My guess -  a bearing puller

All the best _ Bill

Surely it can't be a bearing puller, It doesn't look strong enough. It looks like it grips something and I can only think of an ampmeter, but I dont know why an ampmeter would need to be in this?? I am intrudged by the counter sunk screws... Maybe its a holder for polishing something??

Grrrrrrrrr

This is great  , you got me trying to remember anything I found difficult while working on the bike, trying to guess when I would have needed your invention... no solution to the riddle yet.

Drum roll please....Dave is correct, drive-side main bearing puller. However, I will now, also, be using it as a dinosaur egg cup. Groily, thanks for the idea.

It's made from a door hinge, two bits of aluminum, a thick scrap of lexan, some all-thread, and miscellaneous screws and nuts. (No comments about which nut has the screw loose, please!)

P.S.  Apologies if this is more photos than it's worth.

AAHAA!! Thought it was I have made a similiar item for my A10. I used it for setting end float for crankshaft to remove bearing inner race ,But now have a RHP  inner race which has been ground slightly on the inside face so it is a push fit on crankshaft, once I establish the shims needed I  just fit the inner bearing I,m going to use. I also have another home brew tool I have made for my A10 to make life easier. If I can sort out a photo I,ll post on this site. Maybe other owners have similar items in their toolkit & would like to share them with us ?. ....G/F DAVE

Thought that was what it would be having gone through the bearing removal process myself, might look a bit on the light side as has been said but the problem with that bearing is access without chewing up the roller cage.
Wish I'd made one , I bought a proper bearing separator but it still damaged the bearing, a better buy was a dial gauge ( and with a bit of luck I'm sure ) I was able to work out the shims I needed first time.

All the best - Bill

The good stuff about Richard's clever device is the contact area, the pressure gets distributed evenly to the whole bearing, and no damage to edges\rollers.
Yes, more homemade tools posts welcomed !

[RichardL]

Thanks for noticing. I meant to mention the benifits of encircling the entire bearing and pulling by the cage. Also, if anyone wants to replicate this, be sure to notice the bevel on the edge of the circle. this allows grabbing the bearing without smashing the shims.

According the Bill, the official bearing puller damaged his bearing, I did not have that problem, however, it is important to try to adjust the four pulling nuts as evenly as possible because the bearing tends to walk off the shaft. I think this is not a problem, as long as the steps are small, therefore, not distorting the roundness of the inner race. This might be a point for comment by someone with more experience than myself.

Well it's rained all day today, so I got on with making a usefull tool!  Something I have needed to make for a long time to cure the frustration of alighing front and back wheels. It was an easy job, the pictures tell the story but the biggest secret here is using some of those incredibly powerfull NEODYMIUM magnets, you'll find these quite cheaply on ebay. I must say that the tool worked instantly and showed me just how much the Red A10s back wheel was out of line, the blue one was fine!

[LJ.]

Okay... I could not insult your inteligence with the wheel aligner tool as it was a bit obvious... But what is this? I made this very simple tool sometime ago and has prooved useful on occasions.

P.S. The dynamo end cap is only to show the size of the tool!

[bsa-bill]

looks like a tool for screwing up or out a hub bearing retainer.

Speaking of which did you know front and rear are different.

All the best - Bill
