Project Z750 part 15

So, the gas bottle has now arrived, so it's time to see if this heat business really does work for freeing up parts.

of course, if I'm going to heat the caliper with a blow torch, then I dont really want to hold it in my hands, so I set up a vise on a bench, and clamp the caliper into it. now again I dont really want to pull the slide with my fingers so I need to put some pressure on it. to do that I attach a bungee to the slide and stretch it a little and attach the other end to the bench. now the slide is being pulled off by the bungee and the only thing stopping it is the corroded in rubber boot. time to apply the heat.
I turn on the gas and ignite the flame. I adjust it so that it looks really hot (not really sure how to tell, so I'm guessing, but it looks and sounds hot). then I start to play the flame over the caliper where the rubber boot goes through. I try not to burn the boot itself, but if it melts at least the slider should come out, and I can clean up any residue later.

after less than a minute, the slider pings off and lands on the floor, so I turn off the gas, and (using pliers) pick up the slider. It worked, the caliper is now separated, so all I have to do is free up the stuck pistons.

As the piston is stuck fast, I have decided to order a piston puller tool to help get it off. when that arrives, I'll have another go at removing the pistons from the front caliper.

Triathlon Training in the new year

So, my 2019 training has got off to a good start. I'm running regularly and my knees seem to be holding up. I've got a training plan to get me to a middle distance triathlon in September and I am managing the run distances I have set myself. I need to find some longer cycling routes to work and ones with a few hills too, but that shouldn't be a problem. my weekly cycling distance is okay, I just need to move to get my ebike to be doing less of the work. last week I did use my normal commuter bicycle and managed the whole four days as well as my runs, so that was a really good sign. Swimming won't be an issue, I have always found that to be the easy part of a triathlon (not that I'm fast, but I can keep going, and I did manage to swim the distance within the cut off time when I tried the ironman 70.3 last time) The main worry about going longer is my knees. I've got a 10K booked in late January which will test my knees out and I'm hoping that they hold ...

First race of 2019

As I am aiming for a middle distance triathlon in September, I want to make sure that I can complete it before shelling out the (rather high) entry fee. my main concern is that my knees cope with the run section which will be 21 Km (a half marathon). In the past, I have had a bit of trouble with my knees playing up. I thought it was because I had run too much (increased my training too quickly, too many races close together, that sort of thing). So for the last 8 months, I have been trying to acclimatise my knees by running around 5km three times a week To take stock of how my knees are with running, I decided to enter a 10K race. The race I entered was the Bristol Race For Chocolate 10K. It sounded like a fun race and was on 27th January, which would give me plenty of time to train for my main race in September. I wanted a 10K as it is just under half the distance of my target middle distance and if my knees cope with that then I have plenty of time to increase the distance...

Wales 500 Post 2

Day -1 (of the rally) So, tomorrow, Patrick and I will be riding up to set up our campsite ready for two days of (not quite off) roading. I've got my camping gear packed, but I've been getting confused about how to pack things that I will want whilst riding vs stuff to leave at camp. Then I realised that I've never done that before. whenever we've gone on a trip we've always stayed a night and then moved on to the next place. Only once have we set up and stayed in the same place for more than one night, and that was at Assen to watch the MotoGP. Guess I'll get it sorted today. I think I've got everything I need, except a way to pump up my tyres if I have a puncture. I have a puncture repair kit, but no pump. hmmm, will have to think on that. I think I will be taking a rucksack so that I can carry stuff out on the rides with me, but I may try to attach it to the back of the bike instead of wearing it as it might get too hot. Today is wet and rainy...
