Frame mods Plan C ref 5.5 revision F

I looked at the flat plate template this morning, cut out the shape in rough from a length of 8"x1/4" flat stock ... Picked it up and decided it had no place on a hotrod motocycle.....
Change of plan. Length of 7/8" tube in the lathe, squared off at both ends and cut back at 45 deg. Then i cut 2 end slugs with 3/8" dowels to fit into 1/2"x1" flat drops, which will be countersunk and bolted to the 1" slugs fitted to the frame.

Progress

Started the day with a modified plywood mock up of the removable flitch plate to replace the crossbar



Then i found a length of 1.25" screwed rod in the railway yard and turned down a short length to use as slugs in the frame, to fut the plate in place



As i was doing that, a courier arrived with the blower, so i trial fitted it to see if it would go where i want it.... all fits in fine 8)

Frame crossbar

After having a long look and think about how best to replace the under tank crossbar, today i mocked up option two in Grizzy's sketch below







The steel version will extend 3" forward and pick up a fixing from the web of the front headstock casting, a fourth fixing will drop vertically from just in front of the seat hinge mount and pick up the headsteady




This will give 1.5" of clearance between the tanks to let me move the oil line fittings in there and aid cooling!

Seat n feet

Picked up a package from parcelforce this morning that had come from Australia, complete subframe for my Messinger seat, sits a bit too far forward and high for my taste so I'll need to make up a longer front pivot bar and the spring mounts... once the rear guard is fitted.

Blower and SU

Picture of a blown 1936 MG ta that pulled up outside the shop last week have got me thinking.....







1250cc motor 1.5" SU and a Shorrock supercharger, my concerns about reliability dispelled by the driver who told me he was touring around tje coast of Scotland!

The first cut!

With the Sport Scout away for the day at the MOT station in Inverness. I decided today would be a good day to cut the crossbar out of the 101 frame and see if i could get the motor sitting in nicely
















Just as i was fitting the tanks this beaut of a 1936 MG TA pulled up! More pics of it on the Speedshop blog.

Sitting out in the sun shining like a Hobo Nickel

Finally got all the big lumps together in one place!

Introducing the "Hobo Nickel"

74cu" 1940 Chief motor in a 1929 101 Scout frame

On the doorstep this morning

Good straight 101 frame for the '40 motor, not so straight 101 frame on the left to be retubed on the bottom rails and rear for the '33 motor ... and most of another frames worth of castings to build a 45" 101 flattrack special...... one day!

Wheel for the Alchemist

From a late 1960's Honda CB160, nice and narrow so it will fit in between the rockers and won't hit the pivots

Oil pump

Turned up from the US this week, this is for '33 motor... shaft turns smoothly and seems to pump oil 8o)

Any Old Iron

I collected two international parcels this morning. Think I need to build a jig!

Importing more rust

Lower half of a 101 frame coming from Ziggy's and a 101 headstock casting coming from Chicago.. more pieces of the Alchemist jigsaw

Forks n hubs

Indian 101 forks are very narrow.. not much space between the rockers, and the pivot bolts reduce the usable width considerably.
Today I tried a few of the hubs in my parts stash for size.. 741b Scout hub (above RHS) is way too wide.. about 2", a Triumph tiger Cub hub, (below RHS) is a tight squeeze but will fit, then I found what I believe to be a pre war Triumph 3T hub, same size as the 741b hub bit 1.5 " narrower, the drum bolts to a cotton reel style hub so it shouldnt be too difficult to narrow it further and then Ill be able to use the 741b brake plate, shoes pivots and cam tyhat I have in hand... saves cutting up an Indian hub too!

Quality rust

Nothing like a piece of proper 80 year old rusty motosickle to cheer you up on a cold december morning
